During April-May 1991, by using SAT. CFT. and Coomb's methods epidemiological surveillance on brucellosis among human beings and animals in some villages and pasturelands of Su Nan County was conducted. We found out that the serum brucella antibody was positive in 61 cases (19.06% out of 320 human beings) and 49 cases were diagnosed as brucellosis. We also made an investigation on 497 cattle and 1989 sheep with SAT methods. The result showed that 15 sera showing a positive reaction all came from sheep. The rate was 0.75%.
